ISC Class 12 Mathematics: Preparation Tips
The ISC Class 12 Mathematics includes a balance of concepts, regular practice and time management. The Candidates should give priority to calculus, Algebra and Probability as they contribute 60% weightage in the exam.
- Focus on High-weightage topics like calculus (30-35 Marks), Algebra + Probability(22-25 Marks).
- Regularly solve 20-25 mixed questions, in different topics, to increase accuracy and not make the same mistake in the exam.
- Practice the last 10 years of ISC Previous year question paper to enhance the skills of solving questions during the exam.
- The Optional section should be chosen strategically, as Section B is better for candidates in geometry and Section C for those comfortable in economics & statistics.
- In the first 2 weeks, focus on Calculus & Algebra, and in the 3rd Week focus on Probability & Optional Topics and in the final week, on the mock tests.
